“…The performance and smoke results obtained from an electricity generator engine operating on WCOME showed that the smoke reduction, compared to that of conventional diesel fuel, was around 60% for B100 (100% biodiesel) and around 25% for B20 (20% biodiesel) . Dorado et al (2003) conducted an 8-mode test using waste olive oil in a fourstroke, three-cylinder, direct injection, 34 kW engine and results showed that 8.6% reduction in CO 2 , a 58.9% reduction in CO and a 57.7% reduction in SO 2 emissions. However, increases of 8.5% and 32% were observed in specific fuel consumption and NOx emissions, respectively.…”

Biodiesel is one of the most popular prospective alternative fuels and can be obtained from a variety of sources. Waste frying oil is one such source along with the various raw vegetable oils. However, some specific technical treatments are required to improve certain fuel properties such as viscosity and calorific value of the biodiesel being obtained from waste cooking oil methyl ester (WCOME). Various treatments are applied depending on the source and therefore the composition of the cooking oil. This research investigated the performance of WCOME as an alternative biofuel in a four-stroke direct injection diesel engine. An 8-mode test was undertaken with diesel fuel and five WCOME blends. The best compromise blend in terms of performance and emissions was identified. Results showed that energy utilization factors of the blends were similar within the range of the operational parameters (speed, load and WCOME content). Increasing biodiesel content produced slightly more smoke and NOx for a great majority of test points, while the CO and THC emissions were lower.

“…With diesel, it increases fuel lubricity and operates in compression ignition engines with little or no modification [13]. Furthermore, biodiesel offers compensations regarding engine wear, cost and availability [14,15]. Pollutants produced are less harmful comparatively [16,17].…”

In this work, biodiesel obtained from the transesterfication of Jatropha seeds and Fish wastes is used as an alternative fuel to diesel in stationary single cylinder diesel engines. The biodiesel obtained has good ignition ability due to its relatively high cetane number compared to that of conventional diesel fuel. The performance, combustion and emission tests using Jatropha Oil Methyl Ester (JOME), Fish Oil Methyl Ester (FOME) and their blends (20% JOME and 20% FOME) with diesel were carried out at constant speed and variable loads condition. The results showed that both blends could be used as fuels for diesel engine without any major modification on the engine. Carbon monoxide (CO), UBHC and smoke emissions were observed to be lesser at all loads for both the blends compared to diesel fuel, while NOx emission was slightly higher. JOME blend was found to be better than FOME blend.

“…This is an equilibrium reaction where an organic oil, or triglyceride, can be processed into biodiesel, usually in the presence of a catalyst, and alkali such as potassium hydroxide [15,16]. Biodiesel, which is produced from vegetable oils, animal fats or waste cooking oils has been shown to yield lower emissions of particulate matter (PM), unburned hydrocarbon, carbon dioxide, carbon monoxide, polycyclic aromatic hydrocarbons (PAH), and nitric polycyclic hydrocarbons (nPAH) than petrodiesel [17].…”

KEYWORDSGarden cress seeds were analyzed for proximate composition and mineral content. The protein isolate (PI) was evaluated for chemical composition, mineral content, amino acid composition, biological values and some functional properties. The seed oil was evaluated for fatty acid profile; tocopherols and some of physicochemical properties were studied. Seeds were found to contain 29.11% oil and 25.12% protein. Phosphorus, magnesium and calcium constituted the major minerals of the seeds. The protein efficiency ratio (PER) of PI was 2.37. PI was found to possess relatively high values of water and fat absorption capacity, emulsification capacity and foam capacity. The fatty acid profile showed that linolenic acid (41.17%) and oleic acid (26.42%) were the major unsaturated fatty acids, whereas palmitic acid was the major saturated acid. Total tocopherol content of garden cress oil was 150.46 mg/100 g oil. The physicochemical characteristics of oil and biodiesel meet the norm specifications.Seed Biodiesel Erucic acid Amino acid Garden cress Triglycerides
